DETAILED DESCRIPTION

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0022] The present embodiment provides a high-strength, easily detachable combined guardrail, which is used for engineering construction safety. The mitigation mechanism 2 can effectively reduce the impact force generated when a vehicle collides with the guardrail, thereby increasing the safety of the occupants and improving the durability of the guardrail. The assembly mechanism 3 can quickly assemble and disassemble multiple guardrails to prevent them from rusting underground due to being fixed by bolts. This not only improves the applicability of the high-strength guardrail, but also increases the use effect of the high-strength guardrail.

[0023] Reference Figure 1 and Figure 2 A high-strength and easily disassembled combined guardrail comprises a baffle 1, a relief mechanism 2 is arranged inside the baffle 1, an assembly mechanism 3 is arranged outside the baffle 1, the relief mechanism 2 comprises a first column 201, the front of the first column 201 is fixedly connected to the back of the baffle 1, the front of the baffle 1 is fixedly connected to the second column 202, the inner wall of the baffle 1 is fixedly connected to three groups of dampers 203, each group of dampers 203 has three members, the left ends of the three groups of dampers 203 are commonly fixedly connected to a relief plate 204, the front and back of the relief plate 204 are fixedly connected to sliding blocks 206, each sliding block 206 is slidably connected to the inside of the baffle 1, the sliding block 206 can move simultaneously with the relief plate 204, and utilizes the friction generated by itself on the baffle 1 during movement to improve the stability of the relief plate 204 during movement, thereby effectively increasing the stability of the device.

[0024] Reference Figure 1 and Figure 2 The outer surface of each group of dampers 203 is sleeved with an auxiliary spring 205, and ventilation holes 207 are opened inside the baffle 1 and the relief plate 204. The bottom surfaces of the first column 201 and the second column 202 are fixedly connected with weight blocks 208. The ventilation holes 207 can be used for ventilation to prevent the baffle 1 from being blown down when the wind speed is high. At the same time, the weight blocks 208 can use their own weight to improve the stability of the first column 201 and the second column 202 when in use.

[0025] Reference Figure 2 , Figure 3 and Figure 4 The left end of each group of auxiliary springs 205 is fixedly connected to the right side surface of the relief plate 204, the right end of each group of auxiliary springs 205 is fixedly connected to the inner wall of the baffle 1, and the upper surface of each weight-adding block 208 is fixedly connected with a reinforcement block 209. The inner wall of each reinforcement block 209 is fixedly connected to the outer surface of the first column 201 and the second column 202. The reinforcement block 209 can increase the fixed connection area between the two weight-adding blocks 208 and the first column 201 and the second column 202, thereby improving the firmness of the connection and preventing the connection from breaking after long-term use.

[0026] Reference Figure 1 and Figure 3 The assembly mechanism 3 includes two slots 301, each of which is opened on the back of the first column 201. The upper surface of the baffle 1 is fixedly connected with a warning light 210, and the left side of the baffle 1 is fixedly connected with a reflective strip 211. The light emitted by the warning light 210 and the reflective ability of the reflective strip 211 can effectively attract the attention of vehicles and pedestrians, preventing collisions due to blurred vision at night.

[0027] Reference Figure 3 The interior of the first column 201 is slidably connected to the two limit blocks 302, and the back of each limit block 302 is fixedly connected to a stabilizing block 306. Each stabilizing block 306 is slidably connected to the interior of the first column 201. The stabilizing block 306 can move simultaneously with the limit block 302, and use the friction generated by itself on the first column 201 when moving to improve the stability of the limit block 302 when moving, thereby further increasing the stability of the device.

[0028] Reference Figure 3 The side surfaces of the two limit blocks 302 that are close to each other are fixedly connected to the return springs 303, and the ends of the two return springs 303 that are close to each other are fixedly connected to the inner wall of the first column 201. The left side surface of each limit block 302 is fixedly connected to an auxiliary push plate 307, and each auxiliary push plate 307 is slidably connected to the inside of the first column 201. The auxiliary push plates 307 can provide a good force point for the limit blocks 302, increasing the convenience when the limit blocks 302 need to be pushed. The limit blocks 302 can be driven to move by moving the auxiliary push plates 307, thereby increasing the convenience of the device.

[0029] Reference Figure 4 An auxiliary block 304 is fixedly connected to the front of the second column 202. Two through holes 305 are provided inside the auxiliary block 304. A firming block 308 is fixedly connected to the outer surface of the auxiliary block 304. The back of the firming block 308 is fixedly connected to the front of the second column 202. The firming block 308 can increase the fixed connection area between the auxiliary block 304 and the second column 202, thereby increasing the firmness of the connection between the two parties and preventing the possibility of loosening or breaking of the connection after long-term use.

[0030] Working principle: When in use, first move the device to a suitable position, and support the baffle 1 through the first column 201 and the second column 202. The weight block 208 can improve the stability during support. When it is necessary to combine, take the same device and push the auxiliary push plate 307, thereby driving the limit block 302 to move and retract it into the first column 201. At this time, insert the auxiliary block 304 into the slot 301, and then release the auxiliary push plate 307. Use the reset spring 303 to push the limit block 302 to reset, so that the limit block 302 is inserted into the through hole 305, and use the limit block 302 to limit the position of the auxiliary block 304 to prevent the possibility of splitting after combination. When the vehicle hits the relief plate 204, the relief plate 204 will move toward the inside of the baffle 1, and at the same time The damping effect produced by the cooperation of the damper 203 and the auxiliary spring 205 can gradually alleviate the impact force. The sliding block 206 can increase the stability of the relief plate 204 when it moves, thereby realizing the ability to alleviate the impact force and effectively reducing the damage caused to the occupants and the guardrail by the vehicle during a collision. When the guardrail needs to be disassembled, the two auxiliary push plates 307 are pushed, and then the two limit blocks 302 are moved out of the through hole 305. At this time, the auxiliary block 304 can be separated from the card slot 301 to realize the ability to conveniently disassemble the guardrail. The light of the alarm light 210 and the cooperation of the reflective strip 211 can remind the vehicle at night, which not only improves the applicability of the high-strength guardrail, but also increases the use effect of the high-strength guardrail.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
